DASH CONTROL FOR CARBURETORS.

Application filed November 17, 1923.

To @ZZ whom t may concern:

Be it known that I, ALBERT WAGNER, of Norwood, in the county of Hamilton and State of Ghio, a citizen of the United States,

Y have invented .certain new and useful Improvements in'Dash Controls for Carburel tors, of which the following is a specification.

This invention relates to devices for conn trolling the carburetor of an automobile engine from the instrument board of the vehicle, and the object of vthe present improvements is to provide a mechanism which may be produced and installed at a low cost, simplicity and economy in construction being attained without any loss of efficiency in operation. The invention is illustrated in the annexed drawing and is hereinafter described, and it consists in certain novel features which are particularly pointed out in the appended claims.

in the drawings, Fig. 1 is a sectional elevation of a controlling device embodying my present improvements,

Fig 2 is a front elevation of the dial plate,

Fig, 3 is an elevation ofthe clamping or backing plate,

Fig. 4 is a plan view of the blank from which a coupling joint is formed.

in the drawing, the numeral 1 indicates the stem of the mixing valve of the carburetor carrying a head 2 which is engaged and actuated by a fork 3 on the lower end of a rod 4, all of these parts being of wellknown form. 5 indicates the dash of the vehicle having an opening 6 therethrough to accommodate the controlling shaft, and 7 indicates the instrument board which is shown as consisting of a metal plate having a forwardly projecting flange 8 along its lowei` edge, a wooden block 9 being disposed against the front side of the plate to reenforce the 'same and provide a bearing surface for the clamping plate.

A dial plate 10 and a backing clamping plate 11 are disposed at the opposite sides of the instrument board, and depend below the same, screws or bolts 12 inserted through openings 13 in the dial plate and openings 14 in the clamping plate serving to secure the plates in place. The dial plate is provided at its lower end with a forwardly projecting flange 15 which abuts the clamping plate, and the clamping plate is pro! Serial No. 675,396.l

vided along its upper edge with a rearward*y board and will be prevented from buckling'.Nr

The plates are provided with openings 17 and 18, respectively, in their lower portions which constitute bearings for the controlling rock shaft 19. The said shaft is formed integrally from rod material by having'one end bent laterally to form a crank 2O while the opposite end isbent laterally and doubled on itsself to form a handle loop 21, the terminal portion of the loop extending along the shaft, as at 22, and then projecting laterally to form a pointer or index finger 23. A tongue 24 is struck from the upper portion of the dial plate and projects into the path of the pointer, as shown in Figs. 1 and 2, to constitute a stop limiting the movement of the pointer in both directions. The

y shaft 19 is, of course, threaded through the openings 17 and 18 and journals therein, its forward end portion extending through the opening 6 in the dash, as shown. To Aprevent endwise movement of the rock shaft, a metallic washer 25 is secured thereon'by swaging or otherwise and bears against the front side of the dial plate, while a fiber washer 26 is secured upon the shaft at the rear side of the plate the frictional engagement of the fiber washer with the plate holding the shaft in a set position. Upon the dial plate concentric with the shaft are a series of digits 27 arranged in arithmetical progression while at the upper end of the plate at oposite sides of the tongue 24 appear the legends Lean and Rich rEhe rod 4 has its upper end secured in a coupling sleeve 28 and in the upper end of said sleeve is secured the lower end of a stem 29 which forms one terminal of a cra-nk 30 the longitudinal axis of which is disposed at a right angle to the longitudinal axis of the crank 20. The cranks are connected by a coupling 31 so as to constitute a universal joint, the coupling being formed from a single integral blank consisting of a central rectangular body 32 having a substantially semi-circular lobe 33 extending from each side, an opening 34 being formed through each lobe. The alternate lobes are bent in opposite directions to lie at right angles to the body and the alined openings 34 then receive the cranks 2O and 30, as will be the universal coupling, `the dial plate, and l the clamping plate may each vbe stamped from a 'blank 'of sheet metal byV a single operation.

Having thus fully described my invention,

fvvhat l claim as new and desire to secure by Letters Patent of the United States is :W l. In a control mechanism of the class described, the combination of a rock shaft vvformedfrom a length of rod material having one terminal disposed laterally to conystitute a crank and its other terminal bent laterally and doubled upon itself to form a handlemember and then projected laterally -to constitute a pointer, means for coupling the'crank to a device to be controlled,

`and indicator means cooperating with the pointer. i

2. ln a control mechanism of the class described, the combination of a rod con* nected'with and rising from a device to be controlled, a crank at 'the upper end of said rod, a rock shaft having a crank at its front end disposed in angular relation to the first-'mentioned crank, a coupling connecting said cranks and consisting of a rectangular body and lobes projecting from its edges at right angles to its faces, the alternate lobes extending in opposite direc-tions and receiving the respective cranks, the terminal at the lrear end of the rock shaft being laterally bent and doubled upon itself, then projected to form an indicating means for setting same.

3. ln a control mechanism of the class described, the combination with an instrument board of a dial plate bearing against one side of the board and having a flange at its lower end projecting wunder the board lin spaced relation thereto, a clamping 'plate ybearing against the 'opposite side of the boardand Iagainstsaid flange Yand provided at its upper end with `arretaining lip 'to engage a fixed lpart on the board, means for securing the dial plate and the clamping plate together, a rock shaft mounted in and extending through said pla-tes below the board, means for setting said shaft, and means for connecting the shaft with a device to be controlled.

t. ln a control mechanism ofthe class described, "the combination of a rock shaft, means for connecting the shaft to a device to be controlled, a dial plate providing a bearing forthe shaft, a lclamping plate coacting With the dial plate to suspend the shaft on a fixed support, the dial plate having notations upon its face concentric with the shaft, a pointer carried by the shaft, and a tongue struck from the upper part of. the dial plate and projecting into the path of the pointer.

ln testimony 'whereof l hereunto alii); my signature.

ALBERT WAGNER.
